In which generation were silicon chips first 3) Third generation
used in computers?
There are five generations of computers
1) First generation
2)Second generation 1. Vacuum Tubes where used for circuitry and magnetic drums
3)Third generation for memory. They often malfunctioned because of the
4) Fourth generation excessive heat they generated. Punched cards were used
for input, and the computers printed out the outputs.
2. Transistors were more reliable and economical. The
smaller electronic components in the second generation
could
maintain two states, "Off" and "On," represented by the binary
digits 0 and 1, respectively. Second-generation computers still
relied on punched cards for input and printouts for output.
Tapes and disks were used for storage purposes.
3. integrated circuits enabled the development of
computer systems that were cheaper, faster, smaller, and
more reliable. Users interacted with third-generation
computers using keyboards and monitors that
communicated with the other components of the
hardware and operating systems.
4. Microprocessors include thousands of integrated circuits on
a single silicon chip. This generation of computers is
characterized by a significant reduction in processor size
and, at the same time, a significant increase in capabilities.
5.The fifth generation will rely on A.I., Quantum computing,
or nanotechnology.
Which low-level language corresponds 2) Machine language
one-to-one with assembly?
Machine language is what the Computer reads
1) Translator language
2) Machine language A compiler translates source code into machine language. A
3) Compiler language compiler checks source code for errors before translating it
4) Programming language into object code.
Compiled languages are also known as programming
languages. A compiler takes all instructions written in the
program and translates it all at once into machine code.
Interpreters translate and execute source code into
machine language one line at a time. If the interpreter
finds an error, the process is terminated at the statement
containing the error and displays an error message.
, What is a cloud model that delivers 2) SaaS
third-party software such as email or
games There are Three Service types
through the internet?
1) Infrastructure as a service (IaaS) The IaaS model
1) IaaS provides access in a virtualized environment and the
2)SaaS computing
3) RFID resources are composed of virtualized hardware.
4) PaaS
2)Platform as a service (PaaS) In the PaaS model, customers
have access to a platform that supports the development
and management of web applications.
3) Software as a service (SaaS) With the SaaS model, the
software is licensed to customers with subscriptions and
central hosting. Some examples include Gmail, Google Docs,
and Microsoft Office 365.
What is one of IT's roles in globalization? 4) It allows companies to reach a wider customer base.
1) It provides support for JIT Advancements in computer hardware, software, and
manufacturing. networking have increased people's ability to
2)It allows companies to achieve ISO access information and reach economic
9001:2008 certification. potential.
3) It provides tax havens for companies.
4) It allows companies to reach a wider
customer base.
Which category of computer has an 3) Desktop
external flat screen monitor, optical disk
drive, and a large capacity hard drive? Computers are categorized based on their size and
processing speed.
1) Handheld
2) Laptop Supercomputers are the biggest and fastest computers,
3) Desktop designed to process huge amounts of data.
4) Mainframe
Mainframe computers are designed to support hundreds or
thousands of users simultaneously.
A workstation is a single-user computer designed for
technical or scientific applications.
A microcomputer is more commonly known as a personal
computer. It is a general-purpose computer for individual use.
Desktops, laptops, and handheld or mobile devices are all
microcomputers.
